Ok, so there's a new hotfix for Civils 3D for the ribbon.
It says you should have service pack 1 installed before you install this hotfix. Well unless I'm being blind, there isn't a SP1 for civils!
Are you refering to the AutoCAD 2012 Performance Slowdown hotfix menioned under "Data and Downloads" of Civil 3D
Here it mentions that the hotfix applies only to the shipping version.
